(February 2019). 1 Native Range and Status in the United States Native Range From CABI (2019): “C. destructor ranges over 2 million km2 in its native range from South Australia and the southern parts of the Northern Territory in the west, to the Great Dividing Range in the east (Riek, 1967; Sokol, 1988).” 1 “It appears that yabbies were largely restricted to lower altitude habitats in inland areas of southeastern Australia including the Murray-Darling Basin before European settlement, with the Euastacus spp. found in higher altitude habitats and the coastal river systems.” Status in the United States No records of Cherax destructor in the wild in the United States were found. From CABI (2019): “[…] the specimens [Cherax destructor] came from a crayfish farm in California (USA) […]” From USFWS (2016a): “The yabby was officially listed as an injurious wildlife species by the U.S. Fish and Wildlife Service in 2016 under the Lacey Act (18.U.S.C.42). Importation and shipping between the continental United States and the District of Columbia, the Commonwealth of Puerto Rico, or any territory or possession of the United States is prohibited.” From USFWS (2016b): “Of the 11 species, four species (crucian carp, Nile perch, wels catfish, and yabby) have been imported in only small numbers since 2011 […]” The Florida Fish and Wildlife Conservation Commission has listed the crayfish, Cherax destructor as a prohibited species. Prohibited nonnative species (FFWCC 2019), "are considered to be dangerous to the ecology and/or the health and welfare of the people of Florida. These species are not allowed to be personally possessed or used for commercial activities.” From Fusaro et al. (2019): “Pennsylvania prohibits people from transporting, introducing or importing any fish, bait fish or fish bait including crayfish (PA State Laws, Title 30). It is unlawful to possess, import or sell C. destructor in Ohio (OAC Chapter 1501:31-19). It is illegal to possess, import, sell, or offer to sell C. destructor in Michigan (NREPA Part 413). Illinois lists C. destructor as an injurious species as defined by 50 CFR 16.11-15. Therefore C. destructor cannot be “possessed, propagated, bought, sold, bartered or offered to be bought, sold, bartered, transported, traded, transferred or loaned to any other person or institution unless a permit is first obtained from the Department of Natural Resources (17 ILL. ADM. CODE, Chapter 1, Sec. 805).” This law also states that any interstate transporter is prohibited from transferring “any injurious species from one container to another; nor can they exchange or discharge from a container containing injurious species without first obtaining written permission from the Department (17 ILL. ADM. CODE, Chapter 1, Sec. 805).” The law also prohibits the release of any injurious species, including C. destructor. Wisconsin prohibits the transportation, possession, transfer of, or introduction of all nonnative crayfish (Wisconsin Chapter NR 40). Minnesota lists C. destructor as prohibited meaning that a person may not possess, import, purchase, sell, propagate, transport, or introduce C. destructor (Minnesota Rule 6216.0250).” 2 Means of Introductions in the United States No records of Cherax destructor in the wild in the United States were found. Remarks A previous version of this ERSS was originally published in 2012 and revised in September 2014. From CABI (2019): “Notwithstanding its wide distribution and its invasive potential, C. destructor is still classified by IUCN (2010) as Vulnerable. The main threats to this species are degradation of native vegetation and water pollution as a result of fertilizer and insecticide run-off from agricultural farms, as well as increased predation and competition from introduced alien species. The Australian Fisheries Management Act of 1994 designated the yabbies’ ecosystem as an Endangered Ecological Community, requiring vegetation management, run-off control and extensive surveying; without continued conservation efforts this ecosystem is under threat of irreversible degradation.” 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing From Crandall (2016): “Animalia (Kingdom) > Arthropoda (Phylum) > Crustacea (Subphylum) > Multicrustacea (Superclass) > Malacostraca (Class) > Eumalacostraca (Subclass) > Eucarida (Superorder) > Decapoda (Order) > Pleocyemata (Suborder) > Astacidea (Infraorder) > Parastacoidea (Superfamily) > Parastacidae (Family) > Cherax (Genus) > Cherax destructor (Species)” “Status accepted” Size, Weight, and Age Range From McCormack (2014): “Cherax destructor can obtain a large size of 81 mm OCL [occipital carapace length] and weight 350 grams (McCormack 2008).” From CABI (2019): “The species was demonstrated to mature at the end of its first year of life, […] and attain a similar size to the smooth marron C. cainii in its first year of life (29 mm OCL [occipital carapace length], […]), […]. The life span is at least 3 years and possibly up to 6 years (Souty- Grosset et al., 2006). […] Individual growth is highly variable, and the maximum size of around 3 220 g for adult yabbies is reached within 2 to 3 years (Withnall, 2000). The larger yabbies are males. The chelipeds grow faster than the rest of the body, reaching the weight of 100 g in large males (Lawrence and Jones, 2002).” Environment From CABI (2019): “C. destructor is found in a wide variety of habitats, such as desert mound springs, alpine streams, subtropical creeks, rivers, billabongs, ephemeral lakes, swamps, farm dams, and irrigation channels (Sokol, 1988; Horwitz and Knott, 1995; Austin et al., 2003; Souty-Grosset et al., 2006). The majority of the range of C. destructor is characterized by high summer temperatures and low annual rainfall producing an environment conducive to frequent stagnation and desiccation.” “Environmental Requirements C. destructor is adapted to a wide range of water temperatures, between 1°C and 35°C. It does not grow at water temperatures below 15°C and falls into a state of partial hibernation (i.e. metabolism and feeding cease) when water temperature drops below 16°C (Withnall, 2000). Growth ceases at 34°C and mortalities start to occur at 36°C (Mills, 1983; Morrissy et al., 1990; Merrick and Lambert, 1991; Morrissy and Cassells, 1992). The ideal temperature range for optimum growth is 20-25°C (Withnall, 2000). It tolerates high salinities, with growth ceasing at 8 ppt (approximately equal to 25% seawater) and mortalities starting to occur at 16 ppt (Mills and Geddes, 1980). It tolerates oxygen concentration <1 mg L-1, being able to survive for a short time at 0 mg L-1 oxygen (Mills, 1983; Morrissy and Cassells, 1992). Waters with a pH between 7.5 and 8.5 are preferred; however, yabbies can tolerate a pH of 7.0 and 9.0; a pH of below 7.0 increases the toxicity of dissolved metals within the water column and makes the exoskeleton softer, and a pH of above 9.0 greatly increases the toxicity of ammonia (PIRSA, 2011). Alkalinity and hardness levels of 50-300 mg-1 provide a good buffering effect to pH swings associated with the respiration of aquatic flora and fauna; a lack of calcium in the water results in soft-shelled yabbies (PIRSA, 2011). […] they seem to prefer water with moderate levels of turbidity. […] Secchi depths of 20-60 cm are recommended for the optimal management of farm ponds (PIRSA, 2011). Khan and Nugegoda (2007) showed that C. destructor 4-week old juveniles were less sensitive to trace metals than most other tested aquatic organism, showing 96-h LC50 values of 379 μg L- 1 for cadmium, 494 μg/L-1 for copper, 50 mg L-1 for iron and 327 mg L-1 for nickel.” 4 Climate/Range From USFWS (2016a): “The common yabby inhabits temperate and tropical climates.” Distribution Outside the United States Native From CABI (2019): “C. destructor ranges over 2 million km2 in its native range from South Australia and the southern parts of the Northern Territory in the west, to the Great Dividing Range in the east (Riek, 1967; Sokol, 1988).” “It appears that yabbies were largely restricted to lower altitude habitats in inland areas of southeastern Australia including the Murray-Darling Basin before European settlement, with the Euastacus spp. found in higher altitude habitats and the coastal river systems.” Introduced From Vedia and Miranda (2013): “The first introduction of C. destructor into Spain and Europe took place in Girona (Catalonia) in 1983, involving specimens from California (Souty-Grosset et al., 2006). Subsequently (1984- 1985), another introduction was conducted in the province of Zaragoza, where a population was eventually stabilised in Gordués, near Sos del Rey Católico (Holdich et al., 2009). Because C. destructor is sensitive to aphanomycosis, some of its populations have been eradicated using the crayfish plague pathogen. However, some populations persist to the present day (Holdich et al., 2009). It is believed that there are at least four stable populations in Spain: one in Aragon and three in Navarra (Souty-Grosset et al., 2006) […]. Moreover, this species has been detected in other European countries in recent years. For example, a population was detected in Italy in 2008, and one individual was reported in Lake Geneva, Switzerland (Scalici et al., 2009).” From CABI (2019): “The species was introduced to Western Australia from western Victoria in 1932 (Victorian Aquaculture Council, 1999; Western Australia Fisheries, 1999; Austin, 1985; Morrissy and Cassells, 1992). […]. In 1982, C. destructor was for the first time collected from a wild aquatic system in sympatry with a native crayfish species (Cherax quinquecarinatus) in Western Australia (Austin, 1985; Lynas et al., 2004). By 1985, most known yabby sites were still east of the Albany Highway. They have since then shown a continuing strong spread.

A table of aggression intensity was Experience established, ranging from 1 (chasing) to 4 (intense combat). Crabs of intrafamily association performed more aggressive acts of shorter duration than interfamily, family B was more aggressive than those from families A and C: family C was the least aggressive, which is also the most morphologically distinct strain (a new strain with a red carapace). During the second fighting trail, the intensity and number of fights were significantly different to first fight conditions and also differed among families. Therefore, our results suggest that the aggressive behavior of Eriocheir sinensis is different among different families, and the combat experience has a significant effect on the secondary fight.

The region has a Mediteerranean climate and houses 13 native, obligate freshwater macrofauna species (i.e. fishes, decapod crustaceans and a bivalve mol- lusc), four of which are listed as threatened under State and/or Commonwealth leg- islation. The most imperiled species are the Margaret River Burrowing Crayfish (Engaewa pseudoreducta) and Hairy Marron (Cherax tenuimanus), both of which are endemic to the Margaret River catchment and listed as critically endangered (also by the IUCN), and Balston’s Pygmy Perch (Nannatherina balstoni) which is vulner- able. The region also houses several fishes that may represent neew, endemic taxa based on preliminary molecular evidence. Freshwater ecosystems in the region face numerous threats including global climate change, a growing huuman population, introduced species, destructive land uses, riparian degradation, waater abstraction, declinning environmental flows, instream barriers, and fire.

FOREWORD Recovery Plans are developed within the framework laid down in Department of Conservation and Land Management (CALM) Policy Statements No 44 and 50. Recovery Plans outline the recovery actions that are required to address those threatening processes most affecting the ongoing survival of threatened taxa or ecological communities, and begin the recovery process. Recovery Plans delineate, justify and schedule management actions necessary to support the recovery of threatened species and ecological communities. The attainment of objectives and the provision of funds necessary to implement actions are subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. Recovery Plans do not necessarily represent the views or the official position of individuals or organisations represented on the Recovery Team. This Recovery Plan was approved by the Department of Environment and Conservation, Western Australia. Approved Recovery Plans are subject to modification as dictated by new findings, changes in status of the taxon or ecological community and the completion of recovery actions.

Especially alarming are recent confirmation of two distantly separated marbled crayfish Procambarus fallax f. virginalis populations in Ukraine and indications of more North American cambarids present in the local pet market. The present study aimed to investigate crayfish species availability within the Ukrainian pet trade together with the climate match and risk they represent to the freshwater ecosystems generally and indigenous crayfish species in particular. Altogether, 15 NICS belonging to all three crayfish families were detected. Considering their origin, availability, probability of establishment, invasiveness and further aspects, marbled crayfish and red swamp crayfish Procambarus clarkii appear to be potentially the most troubling.

While recent evolutionary studies have focused on a few of these species, here we provide a comprehensive phylogenetic estimate of relationships among the species within the genus. We sequenced three mitochondrial gene regions (COI, 16S, and 12S) and one nuclear region (28S) from 40 species of the genus Euastacus, as well as one undescribed species. Using these data, we estimated the phylogenetic relationships within the genus using maximum-likelihood, parsimony, and Bayesian Markov Chain Monte Carlo analyses. Using Bayes factors to test diVerent model hypotheses, we found that the best phylogeny supports monophyletic groupings of all but two recognized species and suggests a widespread ancestor that diverged by vicariance.

  • Wellington National Park, Westralia Conservation Park and Wellington Discovery Forest
    WELLINGTON NATIONAL PARK, WESTRALIA CONSERVATION PARK AND WELLINGTON DISCOVERY FOREST Management Plan 2008 Department of Environment and Conservation Conservation Commission of Western Australia VISION Over the life of the plan, a balance will exist between the conservation of the planning areas’ natural values and the public demand for recreation and water supply. The area will make an important contribution to reservation of the Jarrah Forest, where natural values, such as granite outcrops, mature growth forest, ecosystems of the Collie River, and our knowledge of them, will be maintained and enhanced for future generations. Visitors to the area will enjoy a range of sustainable recreation opportunities in a variety of forest settings, and provide a benefit to the regional economy. The community will regard the area as a natural asset and will have a greater understanding of its values, and support for their management, through the Wellington Discovery Forest and other education and interpretive facilities. The ancient landscape of the Collie River valley will be recognised as a forest environment of great visual aesthetic appeal, and for its rich Aboriginal heritage, which will be kept alive through the active and ongoing involvement of local Aboriginal people. ii PREFACE The Department of Environment and Conservation (the Department) manages reserves vested in the Conservation Commission of Western Australia (Conservation Commission) and prepares management plans on their behalf. The Conservation Commission issues draft management plans for public comment and provides proposed (final) management plans for approval by the Minister for the Environment. The Conservation and Land Management Act 1984 (the ‘CALM Act’) specifies that management plans must contain: a) a statement of policies and guidelines proposed to be followed; and b) a summary of operations proposed to be undertaken.

Routine astacological surveys in northeastern New South Wales have revealed four new species of crayfish. Three species are allied to the “setosus complex”, a group of small and poorly spinose Euastacus previously recorded only from Queensland: E. girurmulayn n.sp. from the Nightcap Range, E. guruhgi n.sp. from the Tweed volcanic plug and E. jagabar n.sp. from the Border Ranges. These three species are differentiated chiefly on features of the sternal keel, spination and antennal squame. Euastacus dalagarbe n.sp., recorded from the Border Ranges, has affinities with a growing group of crayfish displaying morphological traits intermediary between the setosus complex and more characteristically spinose Euastacus. It differs markedly in spination of the chelae, and in the nature of the lateral processes of the pereiopods. All of these taxa occur in association with the much larger and more spinose E. sulcatus. An unusual crayfish specimen of uncertain status is also discussed. COUGHRAN, JASON, 2005. New crayfishes (Decapoda: Parastacidae: Euastacus) from northeastern New South Wales, Australia. Records of the Australian Museum 57(3): 361–374. Recent taxonomic revision of the genus Euastacus (Morgan, distinct from the setosus complex, being medium to large in 1986, 1988, 1997) resulted in both the description of several size and of moderate to strong spination. Recently, increased new species and synonymies of others, including the sampling in the region extended the distribution of E.
